Pay-per-call employee data API on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to employee data records via the x402 payment protocol. The specific resource `/api/v1/employees/147` returns JSON data for employee ID 147 when called with a POST request and a valid X-PAYMENT header containing a USDC micropayment on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. Payment is handled natively via x402: no API keys, no accounts, no rate limits. The caller simply attaches a USDC payment (on Base L2) in the request header and receives the response immediately.
The x402 challenge confirms the endpoint is live and accepts the "exact" payment scheme on the Base network. The asset address `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` corresponds to USDC on Base. The maxAmountRequired of 20000 base units equals $0.02 (USDC uses 6 decimals). Documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the exact schema of the employee record returned is unknown.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no example responses, and no description of what the employee data object contains. All doc/pricing/README pages return only 'Connect wallet' with no useful content.
Warnings
- —No documentation available — all doc pages render only 'Connect wallet'
- —No OpenAPI or output schema provided; the structure of the employee record is unknown
- —The /api/v1/employees/147 path is not listed among the advertised APIs on the landing page, so its purpose and data contents are unclear
- —No SLA, rate-limit, or uptime guarantees documented
